I brought the M home today, drove it about 2 miles to my house from the garage. It started great, it did have variable throttle but not that much...it seemed to only want to go up to a certain speed in gears 1-4, my wife followed me and said I didn't do more than 5mph. Do I need to replace the governor spring, do I need to adjust the carb? It ran great I just didn't have the throttle it should. It does have a distillate head but I have brand new step head pistons in it to make up for that, any help would be appreciated. Thanks Jim and anyone else that can give advice. ~Anthony

4th gear is about 6 MPH or so. 5th gear is the street gear at an amazing 16mph. (do it when feeling alert and sober. Just kidding, I believe throttling back in 5th will be a good solution till you are ready for full throttle. The engines do not spin fast. A strobe tachometer to assess the actual High Idle (wide open no load speed will tell the story) The lever is normally doing nothing for the first 40% of travel, and then it starts to give speed. So the first step is to see if it is at rated RPM (On the Model Tag.) This can also be done with a shaft tach or revolution counter, and a watch or display of time PTO should be at 580 to 600 RPM with no load full throttle.
Diagnosis is the first issue. Jim

hmmm, I don't have any of those tool to monitor rpm I'll have to ask around with some of my mechanic buddies...it sounds though that it was right around the speed it should be. Next question, there was no smoke coming out of the muffler and I have heard about blue smoke/white smoke, is that normal with a new engine? thanks buddy,~Anthony

No smoke is a good thing. A brand new engine will burn off assembly lube in the first 15 minutes or so. after that it should be smoke free for 7000hrs or so if maintained. Jim
