flathead

I have a briggs flathead .10 over the rod oil dipper hits the side of case plus rod hits the cam the rod is a arc 6360 which is stock lenght what can I do to it so it don't hit anything

Head manufactured by PM-1 Custom Shop, Eldorado Springs, MO. Head Is for Jr Dragster 5hp Briggs Flathead. I was told used with 3" bore/ big stroked engine. I measured cc's with Briggs sparkplug installed and measured approx 94cc's. Appears never used, but has had the combustion area...

Two questions about my briggs flathead. First one: I took side cover off to remove governor. There are no bearings anywhere(bearings that go over rod and seat in side cover) Were the some briggs that didnt come with them? Second one: I have attached a pic , can I or should I remove the paint on...

last few points briggs I have gotten had the "magnetron" ? installed on them. From what I see you just simply install the coil and snip the wires coming from the points unit....or at least thats what looks like was done on the engines I had :shrug: Just want to verify that, I popped the...

Well, I can not figure out the throttle linkage on this engine.:shrug: It almost seems backwards with the Gov. Any information on the set up will be greatly appreciated. This engine is a beast. I have to do some modifications :grind: to my VT-7 frame because this thing is huge, but...

Looking for an unmolested block in good shape. Will take a short block or motor, but already have parts to rebuild a bare block. Prefer iron bore, of course, but willing to take a good used Koolbore if original bore. Thanks!

Just wonder opinions on jet size for 5hp flathead? Has header & cold air intake. Live in Florida so low altitudes. Thanks in advance

Briggs 5hp short block, used. starter clutch/ Point type crank, 3/4 tapped & keyed. No holes in side cover, has score on the flywheel side of the bore, otherwise excellent shape. Asking $75 obo plus shipping from Baltimore, Md. as-is Cylinder boring available for $45 extra

I have a 5 HP Flathead Briggs I was going to use on my Hornet but it does not fit (air filter hits frame). It also comes with a new carb on the side. It did fire up but I have not ran it in several years. I am asking $120 or trade for a Honda 6.5 hp Clone. I can ship but would prefer a pickup. I...

Picked this up last week to put in my 1969 Lil Indian. It's probably going to need a carb and gas tank but the block turns over smooth, has good spark and the tins aren't too bad. Model # is 80102 and it was built in 63. If anyone has a carb and tank for this let me know I might be...

I have 3.75hp flathead, got off small tiller. Wasn't running, so took it apart, cleaned up carb, lashed valves, etc and now runs very well. Actually, this thing runs really well, will pull almost 40mph, gets up to approx 30mph quick. When I had it apart, I noticed the cam lobes (plastic cam)...

Up for sale I have a completely rebuilt 5hp briggs engine for sale. Block was blasted and honed, good port job, milled head, great little cam, tillotson hl314 gas carb, fuel pump, strait pipe, new breather and tube, powdercoated tin and all stainless bolts. engine only has break in time on it...

I've run this engine less than an hour. 5 hp Briggs & Stratton flathead with Candy Blue powder coated tins, all stainless steel bolts, billet rod, slapper cam, Tillotson dbl. stack carburetor. Puts out appx. 12 HP.. The yellow oil fill caps were changed, otherwise it's as shown in the pics...

Hey OldMiniBikes!, I just acquired a DIY chopper build from some guy off of CL locally. It has a 3.5 Briggs. It's a lil rough to the eye but I'd like to get it fired up so it will run smooth :scooter: . It was very dirty with lots of grime and varnish in the tank/carb. It would fire but shut off...

Got this motor with no fly wheel no spark plug, took out the governor cleaned it up got a billet rod new magneto coil bought a used flywheel with a key and cup and bought a brand new spark plug and screwed it in. I then turned it over and see no spark.. There's very little compression what could...

Has anyone experimented with omitting one of the two compression rings on the old aluminum bore flatheads? Im just kicking around the idea, to see what happens to bore life. I have disassembled quite a few of these old engines, and noticed the vast amount of carbon build up usually stops at...

is there any carbs I can use that just bolt on, I just would like to be able to run a seprate gas tank thanks in advance, jason
