Carby for a Hayter with a Tecumseh BVS 153 Engine

[amatureleccy]

Hi everyone.  New to this forum and delighted to be in the comapny of great small engine enthusiasts who are so generous with their expertise. 

I have a Hayter lawnmower with a Tecumseh BVS 153 engine on it.  It is old and has not worked for a long time - but the deck is in great condition.  When I spray of bit of juice into the spark plug chamber, it fires up and sounds quite healthy.    But the carby is in a dreadful state and I need to replace it.

The carburetta is has markings on it "Dellorto FHC20 13A".  It doesnt have a primer bulb on it.  I have googled and cannot find anything that look like it.  Most Tecumseh Carbursttas that I see do have primer bulbs.

Will it be ok to simply replace a non-primer carby with a new original Tecumseh carby with a primer bulb -is it a straight forward swap?

A bit of futher information. 

If I have read the lable properly (its a bit scratched) the engine model number is "BVSR 153  ES E – 41011C S9081C".

And the markings on the carburetta is "FHC020 13A" - I just cant find that on google. 

Thanks all.

Hi amatureleccy, and welcome to TGMF.

I have scrapped so many of these over the years, now wishing I had kept them.  Do you have any mower shops local to you, they might just have a scrap machine with this engine on for a few quid, or they might just be glad to get rid of it.  No guarantee the carb will be good though.

Regarding your original question, I haven't tried putting a primer version on one myself, they tend to be more of the fixed speed setups rather than having a throttle.
