it's smoking AGAIN

toadady · 08-27-2011, 09:05 PM

purchased my G2 smoking, put in new rings,valves,valvestem seal, ect, then year later i got busy with remodel and let it run low on oil, so back apart, punched out .020/.50mm, ran it month with Formula Shell 10w30 then changed the break in oil to Mobile1 10w30 full synthetic, this was a week ago, thursday oil light flickered and it was low, put in 3/4 of a qt of oil and now it's smoking. grrrr.

These engines are very sensitive to being overfilled with oil. If adding 3/4 qt. to top it up actually overfilled it, check your airbox to be sure it didn't push the excess in there and soak the air filter element.

Synthetic oil is an excellent lubricant, far superior to standard oil. It can lubricate a little too good at times. Small engines are not as tight internally as automobile engines. The superior flow characteristics of synthetic can allow it to slip by seals and rings (like your new cylinder bore) and cause leaking and oil consumption.

Check your air filter and clean/replace as needed. Drain out the engine oil and put in 1 qt of your favorite brand of standard oil and run it awhile longer. After the rings wear in and seal a little better, you should be OK to switch to synthetic oil.

i'm no stranger to full syn, i preferr it too, so with a allsports lift where should the oil level be?

With the cart lifted, the engine is tilted and the oil level reads low on the dipstick. Filling it to the full mark overfills the crankcase. Current wisdom is to dump your oil, put in 1 qt and mark your dipstick at the new level.

Hey Gmb74!! With my G9 lifted, after doing an oil change and adding 1 qt the oil wont even register on the dipstick, so i never know what is truly in there. Any suggestions!

well parts are on the way, it used over a quart and a half today with the kids running around smoking the mosquitoes out, had to take the plug out three times to wire wheel off the carbon on the electrode. i just can't see what changing oil types would do this, i guess I'll find out tomorrow night when i get the motor out and apart.

motor is back together, old rings had a end gap of .014, maximum is suppose to be .007, so the rings were gone, I have put a couple heat cycles through it so far today, i want to put a couple more through it before i let the kids on it.
