Hey guys,

First of all, I apologise if this has already been covered. I searched but could not find.

I have a Victa 50th anniversary model that has developed a problem with cold starts.

This thing has been great & usually starts on choke first or second pull, but now forever pulling & finally starts usually by moving lever towards hot run. When it finally starts & warms it sounds & runs well, all throttle positions respond as normal. I have checked the throttle position on all points in carby & seems all ok? When warmed up & running it starts easily after that.

Any ideas or suggestions on this issue would be much appreciated

Thank you.

Possibly could benefit from a carby clean out.I don't think that that would hurt it.It could well be some junk in it.
That would be the first thing I would do anyway.

I assume these have an LM carby on them? they are usually ok on cold start

Yes they do have a LM carby but as I said it would be the first thing that I look at.

Blumby It certainly is a carby problem but after studying them for countless hours and modifying a lot of them there is nothing I can think of that would cause a cold start issue. There is no simple fix. Modifying the throttle cam would probably fix it but it isn't a simple fix

try popping off the muffler and have a look down the spout , might be a scored up piston that will do it everytime , not bad enough that it wont run , just hard to cold start

Thank you all for your replies & suggestions.

I have not had a chance to look or do anything with it since my first post.

I will probably give a carby clean out, it did actually in the past have an over rev issue, so a scorched piston also makes sense ?

Cheers guys.

for sure yes , and most times it is the easiest place to begin . if it looks good down there then it is worth pursuing . if its scored then we can chat about that too .

no comp' no bang or squeeze
