2hp to 3hp conversion

I've noticed that the 3.5 horsepower has a different chamber is this going to be advantageous on a two horsepower motor, possibly fly cutting it to get the cwinch back down or maybe that is a mistake on a small motors

When you say sump cover I'm assuming your meaning the side cover, can the factory one be machined for a roller bearing or ball bearing or is there not enough material there

Your time and effort would be better spend reshaping the intake port to eliminate the dead pockets in the corners and do a slight round-over of the cylinder wall where the combustion chamber part of the head meets the deck.

BTW, this is a ball bearing side cover;

 

[Bluecamaro]

Are there any camshafts available for these motors, is there a nickname for the smaller block is this what they are referring to as an L head

 

[sparkwizard]

L head refers to the valves in the block, making the cylinder/ combustion chamber resemble an inverted "L". We call it a "flathead".

Gutless until modified still underpowered after modifications.


You have options for a flywheel/springs then a carb/header besides a ball bearing pto that is it. Everything else will be done hackjack backwoods style. I welded a cam that sounded great.

 

[Bluecamaro]

Is there a p/n on the flywheel?, cam reminds me of what chevy used on some small block timing gear sets in the late 70s

Sorry I missed your reply ARC 6605 3hp diameter. They are not the cheapest things.
