Hi all,
I am planning for convertion project on the ASP 1.8 4st.
I guess the carb for it is walbro wt456 but can DLE 30 carb be used ? or is it different between 2st and 4 st ?

Another is, do you guys know what would be the best replacement for wt-456-1 ?
I found that the carb is no longer available.

thanks in advance

Walbro model numbers make no sense. I have no idea what the difference might be. Here is a list of walbro carbs that have an accelerator pump. The pump is a very good thing:

Walbro catalog and here is the list of Wt carbs with accelorator pumps, and hi and low needles and no primers.

If your 30cc liked the carb you have it will be about right for the 1.8 (29cc). If the carb is to big the adjustments get to sensitive, to small and you don't get maximum power.

Here is a link to walbro, click on the series you want and look around.

Look around EBAY for a carb that is 10mm or under and is New Old Stock. They are cheap. You may find your WT 456-1 there. Shipping may be an issue for you though.

Remember you need to run a lot of oil in your mix on a glow conversion, 15 or 20%? Maybe someone can comment on this?

Good Luck

20:1. Don't use any less than that for a plain big end. I've read that 12:1 has been used on a Moki conversion. My 180 FS ASP is happy on 20:1 though. It's still only 50mL per Litre (not a lot of oil) compared to glow fuel, which is 4:1 or 5:1.

Thanks.
Now am having trouble with the planes
The cheapest around is 30cc ones. and 1.80 won't be good right ?
