Having a look at a HT27 for a friend. It starts and runs well but it smokes I would say excessively. That is the reason they wanted it checked. I know nothing about these machines apart from what I have read on the net.
It starts like a dream. First pull believe it or not. I have had it for a few days and tried it a couple of times. Flick the choke and it just fires and runs then blip the throttle and the choke comes off and it idles nicely. It runs a Walbro carby which has no adjustment apart from idle speed.
From what I have read they are classed a semi/commercial machine. I tipped out the existing petrol and run my 50:1 mix. No difference to the smoke. I checked the air cleaner and today I removed the exhaust looking for any build up. The port was very clean and the piston and cylinder that are visible look good. It only has one ring which contrasts what I have read about them.
Tomorrow I will try a compression test.
What are your thoughts?
The barrel does come off separately so I was thinking of trying a new ring to see what happens.
