Carbs and Poor starting

[Rubin215]

Stop being a fanny; adjust your valves properly and sort your choke.

The whole thing, start to finish will take you 2 hours.

Valves generally tend to hammer down and get tight, rather than loosen up, so if you have tight valves on startup you will be losing compression, which is a common cause of hard starting.

Once fired the valves heat up, grow a little in length and stay sealed for a while.

Valves growing in length makes the clearances tighter rather than looser. If you are losing compression when cold you'd be losing even more when hot.

Good point, what was I thinking. 😜
