Thank you, that was a good read on the valves.

When I took my plug out it was toast, changed it last summer. You can see it's running rich. I put it back together and it fired up a lot easier with new plug, but I know the valves need adjusted there is 5900 miles on it. So there is only two valves intake and exhaust, so if I have my pistol dead top of stroke with valve up then it's ready to loosen and adjust, then repeat for next valve, I just want to make sure I don't want to do something wrong and it won't run. Probably don't need the part's I ordered but I will keep them. Here's picture of old plug.

I think I'm going to put it back together and see about taking it to a shop and let them adjust them. I don't want to mess something up. I have rotated piston up two different times to check clearance on the up stroke and I can't get a gauge in but the motor is cold.

Well turning motor fan counterclockwise until valve is at top then move fan another 3/4 turn to make sure the lobe is off valve. I don't have any room at all to put a gage in It. seems like it keeps contact and no opening. Would this cause it hard to start but run fine once started.

Ok thanks for the reply, I already ordered the parts will be here Tuesday but will go ahead and see if they are set at 5 thousands. Thanks

Any help on this at all would help thanks, I bought OEM parts to put on it. My next thing to check if this don't work is check my valves to see if they need adjusted, but taking the cover off to rotate motor looks like a pain in the but to get to.

Thought I would join to be able to find out problem's with my hisun sector 550. And try to fix it myself. Only use it to drive back and forth to my property.

Got a hisun sector 550 2019 that's got 5900 Miles on it, this year it started to getting hard to start in morning, once I get it started it works good the rest of the day. But to start it in the morning I got to hold the gas pedal to the floor and it will fire up. I replaced the fuel injector but didn't help it. So I just ordered a new air filter and 02 sensor and a maf sensor to put on it to see if this will fix it. Anyone else had this problem. I'm hoping the parts I ordered will fix it. I also bought a new battery to put in it also.
