I found out today the choke works,it just take alot of flips to get the fuel pumped though and there are no issues anymore with the fuel cooking,lol. The engine also runs great swinging a 20x8 at about 7500rpms and an 18x10 several hundred more. The Poulan 46 is definetly worth coverting. Its a rail mounted engine with a compact crankcase,and side mounted carb and muffler. It required no grinding at all really. I used the flywheel center which was the first time I've done this and it turned out to be quite a pain in the butt trying to cut out the center with the magnets on one side of it and steel plates on the other,but I made it work. Although I liked the side mounted carb,I had to rig up 2 springs to hold the carb on because it doesnt bolt onto the engine,but that was no big deal because theres plenty of material to work with on the carb housing. I was also able to use the stock muffler although I had to modify it some,but its better then getting a muffler made and welded up. Anyway......its a good motor and I'd convert another one anyday if I need a 46 sized engine. I did have to adjust the timing a few degrees + or - from the initial 28 degree point to get it to run without a missing at full throttle.
