Par Car problems
I am new to this but here goes.
I kind of fell into this bussiness I live on a golf course and have some mechanical ability so everyone brings there problems to me. The latest on is a 1991 Par car 2 cycle at first is would not run. I checked compression 120 forward and reverse. the fuel system didn't seem to be very good so I bought a pump and it did not improve. Cleaned the lines and the carb. still no improvement. Then a friend told me about a old rupp they had that when ever the crank seals went out it would not run. So I took the motor out and sure enough both the seals were shot. I have replaced them and have it back in the cart. I set the timing acording the the book changed the spark plug and replaced the gas (just because it smelled old) It will run but not like I would expect. It seems like when it warms up it keeps losing power. My rpm tack says it is running about 3000 rpm (no governer on the unit) and I checked the timing with a light looks good Now I have removed the muffler. It seems to run much better. The hand tach says that it is running about 4000 rpm but it is to loud to take out for a test drive. I would replace the muffler if I could find one but I have not had any luck if finding one on the internet so far. I have thought about cutting it in half to clean it out if that would do it. I heard once of burning it on a grill to burn it out? I am not sure if I am on the right track or not? M. Wood |

Re: Par Car problems
It does sound like the muffler is clogged up. Most Yamaha 2 stroke owners with this problem, pull the muffler and burn them off by placing it in a open fire. I'm not familiar with the Par cars at all, so I'm just making a guess in comparison to the Yamaha 2 strokes.

Re: Par Car problems
Thanks for the feed back.
I did get in touch with a dealer and they said the muffler is $503.00. Which I beleive is a little out of line. It is also a retrofit. I am thinking of cutting it open clean it out then weld it back together. I am just not sure I can get it hot enough to get everything out of the inside? Last option is probably a 4" pipe with plates welded on the ends. I will probably cut the old one apart tomarrow. Thanks again for the infomation. |

Re: Par Car problems
Did you cut the muffler and did it help?

Re: Par Car problems
yes I did I cut it at the seam and removed 2 baffles and drilled a 1/2" hole all the way through the center.
It looked very dirty but I could not see all the baffles I would think that there is a need for some back pressure. It does run considerably better but not as good as I would like. I am thinking that the muffler being pluged is probably what took out the crank seals. I think it is probably as good as it can be. not sure of hp but probably only 8 hp if that. |

Re: Par Car problems
That may be all it will do. Mine will run 17 to 20 mph. The engine is around 8hp.
Look on u-tube for a Harley muffler replacement video. I have seen one before and they were using a stinger off of a dirt bike and it worked very well! |
