I mentioned previously about a video with pointers about purchasing a used engine.
I want to speak specifically to the LO 206 but some of this will apply to any kart engine.
The more I thought about it, I'm not sure what I want to discuss would really work well with a video so a post it is.
Things to look at,
1. Overall condition. Is it clean? This just goes to maintenance and detail.
2. If you can start it. Drive it if you can. This step may not be possible.
3. How old is it? Of course you need orange seals. Please, no comments about old seal engines still in good condition. Check the front of the engine for the year of manufacture. First four digits. Two digits on new stuff.
4. Make sure it has a Briggs logo carburetor not a Walbro. I have had a couple of Walbro carburetors in the shop this year. These are legal per 2026 Briggs rules however, not legal per CKNA rules. So avoid the hassle and use a Briggs logo carburetor.
5. Pull the valve cover and look inside. If it looks dirty or almost like a film on the inside that's difficult to wipe away, beware because the oil hasn't been changed regularly. I'm a fan of every race day. Overkill? Maybe but my engines look new. Don't tell me about cost. It's racing. You want to save money then quit racing.
6. If you have the ability, perform a leak down. If the won't let you, walk away. No reason they shouldn't.
7. If you don't have the ability to perform a leak down ask someone ahead of time to help. I was asked by a buyer if I could look over an engine for them. I was happy to help but the seller said no. This was supposed to be one of my engines. I told him to walk.
8. I mentioned this above but ask the local builder or tuner to help. Most will be happy to help you check out an engine.
9. Who's selling it? Local? If so you probably know their reputation.
10. Ask questions. About hours, last rebuild etc.
I get calls all the time about one of my engines. I can check the serial number along with who owned it and tell the last time it was here and what was done to it.
11. NONE OF THESE ARE DEAL BREAKERS. JUST KNOW WHAT YOU ARE GETTING INTO. I buy used/ blown engines all the time. The parts have valve. Briggs makes a replacement for nearly every part except the bowl drain screw and o ring.
12. If you're looking for a good used engine check with your builder. In the past two months I sold two very good red slide engines and an awesome adult engine . I usually have people asking if I have anything.
Just as a reference new engines complete with all accessories except clutch and mount are $1300 upto $2000 from some builders. Used engines should range from $300- $1000 maybe a little more for low run time depending on hours, condition, etc.
Rebuilds range from $300-$400. Mine always include dyno testing and tuning.
Thanks for choosing MGM and remember if it was easy everyone would do it.
