    Predator 301cc 8hp stock timing

    Would anyone know what the stock timing is on HF predator 8hp engines (hemi head). Can't find it anywhere online. Would it be the same as a gx270? 20degrees? The cam I'm running is a 275 which needs 28 degrees timing. The 6627 flywheel has no timing advance. I just want to make sure I'm running...

    Straighten pushrod

    New rod installed. Motor runs strong but it seems like the engine makes more noise than before. Everything was torqued down and checked for clearance. Doesn't seem to have any excessive vibrations. Doesn't sound like rod knock more valve train. Maybe it's just how the new cam sounds? Tommy tech...

    Straighten pushrod

    Not looking for any huge rpms maybe around 6-6500 hopefully. I'm running a 40 series torque converter. Stock carb with larger jet.

    Straighten pushrod

    This cam only calls for 32# springs, these are 50# springs in the kit (blue stripe) i think i have some 35# springs would those be a better choice?

    Straighten pushrod

    I purchased the stage 2 predator hemi 301kit from gopowersports. They don't give you any information on the parts in the description. The rod and flywheel are from a gx270, the cam is from a gx390. The kit came with duel springs which equals 65# and meant for the 308 cam option. I'm just using...

    Straighten pushrod

    Motor specs predator 301 hemi head 8hp stock length billet rod, billet flywheel, .275 cam, 50# springs? (Gopowersports didn't specify the # in there kit I'm assuming 50#) stock compression.

    Straighten pushrod

    I'm building a predator hemi 301 8hp motor. I wanted to upgrade the pushrods and had to buy a cut yourself kit as they don't make a direct size pushrod for this motor. I didn't know the correct way of inserting the ball end into the rod and pressed it instead of hammering it in. Needless to say...

    Which belt for tav2 7" driven clutch

    Cheapest I could find on ebay shipped, walmart.com wants $30 for a belt. I can buy in bulk and get a better deal but only want 1 to see if its correct.

    Which belt for tav2 7" driven clutch

    I went and ordered the 994-80 belt, I trust my new measurement, $10 shipped I can take the risk. I'll report back when the belt arrives

    Which belt for tav2 7" driven clutch

    Now that I have the 7" driven mounted (ebay parts never fit out the box) I have the 6 13/16" center to center. Just so I'm correct I should go 1 belt size above to compensate for the bronze bushing? Come on guys I know this has been done before, can someone explain why belt 994-80 is 1/8 too...
