A little stumbling off-idle but may just need to be tuned.
yep, i give mine a tune up every spring. rotor, plugs, points and condenser. i dwell and time it and check mid season see that it hasn't changed from where i set it. i also did a carb rebuild since i've owned it. my original carb must have had some linkage wear so i switched carbs to the same exact carb that i had on a 72 tri sonic w/the same engine i got in my Nineteen. that fixed my linkage issue.
My timing cover started leaking today -
bummer. i havn't had that problem, yet. but i did get to do a pan replacement (pull engine for that job). the original one i had got a rust hole in it that ya couldn't even see. it was under the paint that had only bubbled a little tiny bit. not enough to notice untill after much inspection to decide where the leak was at.
so the motor mount will have to come out anyway. I'll poke and prod the area, hopefully it's just cosmetic and not a sign of rotting wood underneath or something serious like that.
ya don't even need to poke or prod. if yer ft motor mount bolts take and will torque down. i suspect yer good. if they strip under torque, then it'll be time for inspection. i'm treaddin on thin ice there. one of my bolts torques down fine. the other one, tightens down and stays put, but i bet if i were to really torque on it, i could strip it right out. so i don't do that. i tightened it down snug and marked it so i can see it move, if it does. so far so good. it's stays where i put it at. but i'm still skeptical about the condition of the wood, just not ready to go look at it for obvious reasons.
