When I first got the mower it was running a 5 and 7 and 11 and 54 sprockets. It does seem to work a little better now thou!. Should I change the sprockets any with the 3.5 and 7.?
Leave your pulleys alone and change front sprocket from 16 teeth to 15 teeth and try it, if you need more than that go to a 14 tooth front gear

Ok, I got that wrong. Your gearing seems to be way to high. You could try maybe a 3.5 on the engine and a 7 on the trans. Overall, you are running huge pulleys which add weight to the drivetrain, and slows acceleration and deceleration. Maybe do the 3.5 and the 7 and drill a few holes some what far apart to lighten the load on the engine. Might also want a little more power. If so, try slapping some copper head gaskets on for a little more compression, advance the cam a gear, get rid of the paper filter, maybe velocity stack and high flow filter if you want to spend the $$$, and do a small timing advance key.

Way to slow gearing. Your maxed out, out of the corner Need to probably make engine a 4 to a 4 on gearbox. What is your tire size?

Our tracks are 200í to 225í long the setbup I have now seems to leave me lazy out of the corners. I have a 6 on my engine and 10 on the box with a 16 tooth to a 60 tooth? Any info be great

I have an internally standard 49 Briggs V-Twin with a billet flywheel, I  have fitted the billet aluminium adapter to the Nikki carb with an after market air cleaner (as from EC Carbs). Wondering if someone could give me some idea of what size the main jets might need to be drilled to. Standard they seem to be 1.3mm. I have tried 1.8mm and 2mm but off the line (standing start) the engine bogs and won't pull hard. Any helpful info will be appreciated.

I'd solder up jets, to original size and open up lowside just a touch to get better throttle response,keep an eye on plug readings, if to lean open mains up just a thousandth or 2 and go run it.
